Why do you HotWheels? New to the hobby!

Hey yall, new to the sub & well now hobby. I decided to start stacking hot wheels as I see the market it hot and honestly, it’s giving my huge nostalgic vibes and I love it as a grown adult now 😂 anyway, I started this weekend & picked up the Grand Turismo skyline, the F&F Tokyo Drift set with very good conditioned box & I was in 7/11 getting a water when I seen the GTR so I had to buy it. Why do you guys do it? And how do you guys find about releases?
